WIRE-NAIL. MACHINE.

SPECIFICATION forming part of Letters Patent No. 397,426, dated February 5, 1889. Application filed October 3l, 1888. Serial No. 289,624. (No model.)

To all whom t may concern.-

Be `it known that l, JOHN l5. l'lASTlNGS, of Jackson, Jackson county, Ohio, have invented a new and useful fire-Nail Machin e, ot' which 5 the following is a specification.

My machine is so constructed as to enable it, by means of suitable adjustments, (hereinafter more fully specified) to make wire nails of various sizes. Said machine is also io so constructed as to simultaneously form the head and the point of the nail.

Referring to the accompanying drawings, Figure l is a perspective view of my machine, showing all the parts (with the exception of I5 the feed7 and the cleaner) in their retracted or inoperative condition. Fig. II is a horizontal section on the line Il ll, showing the finished nail. Fig. Ill is a longitudinal i vertical section of my machine, showing the 2o cutters, grippers, pointers, and header as having` just acted and the cleaner and feed about to act. Fig. IV is a lperspective view of the pointers l l may represent the bed-plate, which has L25 standards 2 2, 3 3, and 4, die-seat 5, and the sliding-block seat G. The standards 2 2 and the die-seat 5 are attached rigidly to the bed-plate, while the standards 3 3 and 4 and the sliding-block seat 6 are cast integrally 3o with said bed-plate. The standards 2 2 carry rollers 7, 3,9,10, ll, l2, and 13, the iirst iive being for the purpose of straightening and the last two for the purpose of feeding the wire, while the standards 3 3 receive the main 3 5 shaft 14. One journal of the roller 13 is produced beyond the standard (in which it j our nais) a sufficient distance to admit of its carrying a cog-wheel, l5, which cog-wheel gears with a similar cogwheel on the roller l2, 4o while the other journal of said roller l2 is produced considerably farther than the aforementioned journal and carries the ratchetwheel i6 and the vibratin arm 17. The said ratchet-wheel is shrunk upon the journal, 4 5 while the arm 17 is capable of vibratingt-hereon, said arm being prevented from slidingoft the journal by the washer '18. To the upper end of the said vibrating arm is pivoted a ratchet or pawl, 19, which engages in the teeth 5o of the said ratchet-wheel. A rod or shaft, 20, communicates power from the main shaft 14 to the said vibrating arm. Standards 2 2 receive ordinary set-screws, 2l, which control ordinary journal-boxes, 22. y

The die-seat 5 supports nearly all the fea- 55 tures of improvement in my machinenamely, the grippers and 24, pointers and 26, steel lirici' 27, cani-levers .2S and 29, and steel die or anvil 30. The parts enumerated (with the exception of the steel die) are 6o so constructed and arranged in an excavation,

v3l 3l, on the die-seat that the upper surfaces are flush with the upper surface of the dieseat, so that the plates 32 (shown partially broken away in Fig. Il) may be bolted or 65 screwed to said die-seat, thereby preventing said parts from escapin from the said excavations. The aforesaid gripper-s 23 and 24 and the pointers 25 and 2li are capable of sliding freclyin the said excavation, and have 7o their surfaces 33 33 slightly inclined to a vertical longitudinal plane. lhe steel liner 27 is for taking up any wear on the said gripper and pointer, and is controlled by the setscrcws 34. Levers 28 and 29 carry steel-tem 75 pered pins 35 and 3G, and also steel-tempered cam-pins 37 and 33. lliese takeup the wear by thc gripper-s and pointers for the levers, and are so inserted into said levers that they may be readily detached for th e insertion of 8o new and unworn pins. The can1-pins 37 and 38 are so arranged upon the levers that they will operate to force the pointers together subsequently to the pins 35 and 36, forcing the grippers together, but with a more rapid 85 movement, for reasons to be hereinafter stated. The levers fulcrum in sockets in steel blocks 39 and 40, which are capable of sliding freely in the excavations 3i 3l. The wear of these blocks and levers is taken up by set-screws 4]. 9o and 42. rlhe grippers and pointers are caused Vto bear against pins 35, 36, 37, and 38 by the springs 43, 44, 45, and 46. The springs 43 and 44 are each fastened at one end to the lugs 47 and 43, respectively, which project from 95 the plates 3l. 3l, while their other ends' are fastened to lugs 49 and 50,which project from the grippers 23 and 24 and play in the slots 5l and 52 in the said plates. The springs 45 and 46 are attached to the lugs 53,54, 55, and roo 56 in a similar manner. The die-seat has a projection, 57, which has an excavation adapted for receiving the steel die or anvil 30. A set-screw, 57, takes up any wear of the said die or anvil. Cast integrally with the die-seat are the standards 5S 58, in which journals the shaft 59 of the crank 60. This crank carries upon the end of one of its arms the cutter-stock 6l, in whose lower end is inserted a cutting-blade, 62. This cutter-stock revolves freely upon the shaft 63, and vis provided in its lower portion with an elongated slot, 64, which receives the guiding-bar 65. The other arm of the crank is bifurcated, and has (capable of sliding between the said bifurcations) a sliding block, 66. After the sliding block is inserted between said bifurcations another' block, 67, (which has a screwthreaded orifice that receives a set-serew, 68,) is inserted between said bifurcations, and secured between the upper extremities of said bifurcations by means of screws 69 69. Sliding block 66 also has a screw-threaded oriiice that receives the set-screw 63, whereby the said sliding block may be raised or lowered, thereby giving the crank a longer or shorter vibration, in order to cut the wire into greater or less lengths. To the sliding block is attached a rod or pitman, 69, which connects the said sliding` block with the standard 7 0,

which standard is shrunk upon the tongue 7l of the cam-yoke 72. The cam-levers 2S and 29 have excavations in their rear ends, in which journal rollers 73 and 74. These rollers are caused to bear continually against the trippers 75 and 7 6 by pressure of the grippers and pointers against the forward ends of the levers. Bearing-plates 77 and 7 8 assist in confining the levers to ahorizontal motion. The sliding-block seat 6 carries (in an excavation or channel, 79, provided for their reception) the sliding or header block S0, and the steel liner S1 for taking up the wear ofthe said headerblock. This liner is controlled by the set-screws 82. The header-block carries (in an excavation provid ed for its reception in the forward end of the said header-block) the steel-header 83. Lateral wear of the said header is taken up by the set-screws S4, here shown in dotted lines. A wedge, 85, inserted between the rear surface of the header and the rear surface of the said excavation and controlled by the set-screw 86, takes up all the longitudinal wear of the header. Dovetailed into the rear end of the header-block is the aforementioned cam-yoke 72. A cam, 87, upon the main shaft revolves within said yoke, thereby operating to move the header-block forward and backward. The tongue 71 slides in a tunnel, 88, in the standard 4 of the bed-plate. The said tongue is secured to the cam-yoke by bolt 89. The main shaft 14 carries upon one end a crank, 90, to which is attached, by means of a pin, 91, the aforementioned arm or rod 20. The other end of the main shaft carries the driving-pulley 92. A cleaner, 93, fulcrums upon a rod, 94, which is capable of rotating' in the standards 5S 5S. One end of the cleaner (in the closed state of the grippers) rests partially upon the nail, while the remaining part of said end is in the groove 95 in the gripper 23. To the other end of said cleaner is attached a knuckle-joint, 96, which is also attached to the cam-yoke.

The operation of the machine is as follows: As the wire comes from the reel it is, as aforesaid, passed beneath the rollers 7 and S and over the rollers 9, 10, and 11, for the purpose of straightening the said wire. The end of the wire is then inserted into the annular groove 97 in the roller 13. The object of this groove is to enable the rollers 12 and 13 to bite the'wire with more certainty, and thus to feed equal lengths of the said wire at each vibration of the arm 17. vThe wire is then fed along in a groove, 9S, in the upper surface of the die or anvil 30. lVhen the wire is fed along' sufficiently to project slightly beyond the rear surfaces ol the grippers, the said grippers will (by the pressing of the trippers 75 and 76 upon the levers 2S and 29) operate togrip or grasp the wire, immediately after which the wire will be severed by the cutting'- blade or shears 62. After gripping and severing the wire by the above-described means, the header S3 and the pointers 25 and 26 will operate at the same instant to head and point, respectively, the severed portion of the wire. The conical wheels or rollers 73 and 74 have by this time passed the crown 99 and 100 of the trippers, when the springs 43, 44, 45, and 46 will, as aforesaid, operate to throw the grippers and pointers back into their original position, and at the same instant the cam 37 will operate to draw back the header, and at the same time will (by means of the knuckle-joint 96) raise the rear end, and consequently depress the forward end, of the cleaner 93, thereby instantly and surely ej ecting the thus finished vnail from between the grippers down into a box or keg placed in the excavation 101. Instantly upon the completion of the nail the continued movement of the main shaft will operate to draw the vibrating arm 17 rearward, which, by the engagement of the pawl or ratchet 19 in the teeth of the ratchet-wheel 16, will revolve the rollers 12 and 13, thereby feeding along an amount of wire sufficient to make another nail. The crank 90 has a slot, 102, for adjusting' the feed mechanism for feeding greater or less lengths of wire, so as to make longer or shorter nails. The pointers have cone-shaped notches 103, for giving the required form to the nail at the point. p
